LUBRlCATING DEVICE.

GPECIPICATION forming part of Letters Patent No. 309,6l3, dated December 23 1884.

Application filed J'uly 15, 1884. (No model.)

To call whom it may concern:

le it known that l', WILLIAM J. FAUL, a citizen of the United States, and a :resident of the city and county of N ew York, in the State of New York, have invented anew and useful Improvement in Lubricating Devices, of which the following is a specifieation, reference being had to the accompanying drawings.

My invention relates to that class of lubricating devices in which grease orother lubricating material solid at ordinary atmospheric temperatures, but easily liquefied by friction, is used in the form of a stick 01' Cartridge, and, being fed against a journal, liquelies sufllciently for lubrcation, as required.

The invention consists in a lubricating-cartridge eomposed of two lubricating materials or compounds of different degrees of hardness, the harder material or compound serving as a support to sustain the softer material or compound.

The invention also consists in the conbination, in the l'orn' of a Cartridge, of ashell or body of solid grease or lubricating substance or compound, and an internal core ol' harder material which, while it stil'fens said shell or body is (-apable of reduction therewith.

The invention also consists in the combination, as hereinafter described, of a stick or plug of solid lubricating material, a core of harder material, and a weight enployed to press the grease toward the surface to he lubricated.

Figure l is a longitudinal sectional View illustrating one form ol' a lubricating-cartridge construeted according to myinvention. Fig. 2 is a transverse section of the same. Figs. 3, 4, 5, 6, and 7 are transverse section-al views of various niodifications of the same. Fig. S is a side view, partly in section, of another form of lubrcating-cartridge constructed according to my invention. Fig. 9 is a transverse sectional View of the same.

Similar letters of reference denote corresponding parts in all the figures.

The core or harder material is denoted by A in the several figures. B indicates the body of grease or other softer but yet solid lubricating material, and D designates a weight of metal or other heavy material attached to the cartridge to keep it to its place. The harder part A, which in Figs. 1, 2, 3, eL, 5, 6, and 7 is illustrated as a core, may be composed of any material which, while it is hard and stifl" enough to support the body of grease that it may not be easily broken, is of such a nature that it will be reduced and consumed with the body B in lubrication. This may be acconplishcd by molding said core of a harder and stronger lubricating compound than that used in the body of grease-as, for example, a conipound of tallow, sulphur, and plumbago, which, by varying the quantites of its component parts, may be made of any desired hardness. There are many other lubricating compounds which may be used for the same purpose. In molding or constructing said core it is made a little longer than the body ot' grease, so that it will project a little at one end, as illustrated at i of Fig. l, for the purpose of attaehiigiit and the body of greasc which surrounds it to the weight D by insert ing the said projecting end 'i tightly into a hole provided for it in the said weight. lt may be made of any formfor example, solid and cylindrieal, as illustrated in Figs. land 2, or solid and fiuted, as illustrated in section in Fig. 3, or hollow and cylindrical, as illustrated in section in Fig. 4-. Or this core may be eonstructed of material in sheets, in which case it may be made of any convenient form as, for example, with three radial wings or four radial wings, as illustrated in Figs. 5, G, and 7. Around this core is molded the shell or body of grease B, which may be of any convenient size and form. In the examples given it is illustrated as being cylindrical, that form. seeming preferable. This body of grease should in all cases be conposed of such material that, while it is solid at ordinary atmospheric temperatures, it will be easily liquefied by friction.

Instead of larder lubricating material, which sustains, stiffens, and strengthens, the Cartridge, being a core, it may be reversed, and the softer part may be the core and the harder part the shell, as is illustrated in Figs. 8 and 9. In this case the outside shell or case of harder material is first nolded and afterward filled with the softer lubricant. This 'form of the Cartridge may be ol' any convenient shape. In the example given it is represented as be- IOO ing oylind'ical, that form seeming p'efeable. This grease Cartridge is used' as lubricating devices of its class commonly are, and may be applied to any journal having space enough to admit its free' motion lengthwse in the oilhole.

What I claim, and desire to secure by Letters Patent, is-

1. A lubrioating-cartridge oomposed of two lubrioating materials or eompounds of different degrees of hardness, the harder material or compound serving as a support to sustain the softer material or compound, substa-ntially as herein described.

2. A lubricating Cartridge or stick composed'of a shell or body of solid grease or lubrioating materiaha'nd an internal 'core which, While it stiffens said shell or body, is oapable of reduction therewith, substantially as and for the purpose he'ein described.

3. In a lubricating grease Cartridge, the combination, with the body of grease and a weight, of an internal core, one end of which enters into said weight for the attachment of the body of grease thezreto substantially as 25 and for the purpose hei-ein described. u
